Main BMC for example can transmit relevant main BMC, to the proprietorial information of major state (, configuration information, configuration information), to promote the role of main BMC to be transferred to another BMC, if necessary.Like this, for example, if first node BMC 205 is designated as master, it can be periodically given communication for example, from BMC (, Section Point BMC 305, the 3rd Node B MC 405), so as to promote (future) by main role be transferred to from.
Thereby the arrangement of the frame of describing in Fig. 1 and numbering can not be intended to imply sequence of operation and get rid of other possibilities.One of skill in the art will recognize that and can carry out various modifications and change to system and method.
For example, in the embodiment describing in Fig. 1, a BMC (for example, BMC 206) is can be mainly attached a node (for example, node 101).This is without being this situation.Other embodiment of the present invention can allow single BMC monitoring, management, support and control more than one node.
Turn to now Fig. 2, show the process flow diagram of the illustrative methods of the configurable and fault-tolerant baseboard management controller arrangement of use according to an embodiment of the invention.The method can be implemented as to be stored in uses circuit engineering (such as special IC (ASIC), complementary metal oxide semiconductor (CMOS) (CMOS) or transistor-transistor logic (TTL) technology or its combination in any) fixed function hardware in configurable logic (such as programmable logic array (PLA), field programmable gate array (FPGA), complex programmable logic equipment (CPLD), ) in machine or computer-readable recording medium (such as random access memory (RAM), ROM (read-only memory) (ROM), programming ROM (PROM), firmware, flash memory etc.) the logical order collection in.For example, the combination in any of available one or more programming languages is write for carrying out the computer program code of the operation shown in the method, comprises OO programming language, such as C++ etc., and conventional program programming language, such as " C " programming language or similar programming language.
In the present embodiment, at Section Point BMC (such as Section Point BMC 305 (Fig. 1)) and the 3rd Node B MC (such as the 3rd Node B MC 405 (Fig. 1)) afterwards, first node BMC (such as first node BMC 205 (Fig. 1)) can reach the standard grade.First node BMC can have identification number 1, and Section Point can have identification number 2, by that analogy.
The method can start in processing block 2000.In processing block 2010, Section Point BMC and the 3rd Node B MC can reach the standard grade.In processing block 2020, Section Point BMC and the 3rd Node B MC can pass through I/O extender (such as I/O extender 600 (Fig. 1)) and detect existence each other.In processing block 2030, the algorithm of being realized by the BMC fastener components (such as Section Point BMC fastener components 306 (Fig. 1)) of Section Point BMC can should be born the role of main BMC state based on lowest section point identification number definite Section Point BMC.Having more the 3rd Node B MC of high node identification number can be used as from BMC and moves.
In processing block 2040, first node BMC can reach the standard grade.In processing block 2050, the BMC fastener components of first node BMC (such as first node BMC fastener components 206 (Fig. 1)) can determine that it should state main BMC state based on minimum identification number (that is, 1).In processing block 2060, first node BMC can message transfer to notify it can bear the role of main BMC.
In processing block 2070, still the Section Point BMC with the operation of leading role's look can indicate it to abandon the role's of main BMC response to first node BMC transmission.This message for example also can comprise with Section Point BMC, as the relevant information of the role of main BMC (, system resource configuration, system status information etc.).In processing block 2080, thereby can starting time out period, first node BMC allow any system component to oppose that it bears the role of main BMC.
In processing block 2090, after time out period is gone over without any opposition in the situation that, first node BMC can bear from Section Point BMC the role of main BMC.In processing block 2100, first node BMC can complete to indicate the role that it bears main BMC by transport communication (for example, system status information) in time out period.In processing block 2110, first node BMC for example can periodically transmit relevant first node BMC, to the proprietorial information of major state (, configuration information, configuration information), to promote role who shifts main BMC etc., if necessary.
In processing block 2120, first node BMC may be out of order (for example,, due to firmware failure).In processing block 2130, after first node BMC can not send out message in time out period, at least one in other switching nodes can determine that current main BMC (that is, first node BMC) may no longer work, and determines which node should be new main BMC.In this case, the BMC fastener components of Section Point BMC can determine that Section Point BMC should bear leading role's look (that is, based on minimum identification number).
In processing block 2140, Section Point BMC can state main BMC state.In processing block 2150, the proprietorial information of the addressable relevant first node BMC mainly being transmitted by first node BMC of Section Point BMC to major state, to promote it to bear the role of main BMC.In processing block 2160, Section Point BMC can bear the role of main BMC.In processing block 2170, this process can finish.
Thereby the order of the processing block of describing in Fig. 2 and numbering are not intended to imply sequence of operation and get rid of other possibilities.One of skill in the art will recognize that and can carry out various modifications and change to system and method.
For example, in the above-described embodiments, algorithm can be realized BMC fastener components based on the bright main BMC state of lowest section point identification bugle call (that is, processing block 2020).Yet, this situation not necessarily.In other embodiments, the BMC that has a lower identification number can only be designated as main BMC after current main BMC is out of order.
Equally, in the above-described embodiments, Section Point BMC can to first node BMC transmission indication, it abandons the role's of main BMC response (that is, processing block 2070).Yet, this situation not necessarily.In other embodiments, before sending this message, first Section Point BMC can indicate its " busy " (for example,, in the middle of power supply upgrades).If Section Point BMC indicates its possibility busy, request first node BMC can periodically resend the request that it bears the role of main BMC, until its success.
